Abstract
A neurostimulation system delivers neurostimulation to a patient using one or more primary parameters and one or more secondary parameters. The one or more primary parameters are controlled for maintaining efficacy of the neurostimulation. The one or more secondary parameters are adjusted for preventing the patient from developing neural accommodation. In various embodiments, values for the one or more secondary parameters are varied during the delivery of the neurostimulation for prevention of neural accommodation that may result from a constant or periodic pattern of stimulation pulses.
Claims20
A system for delivering neurostimulation, comprising:
- a stimulation output circuit configured to deliver neurostimulation;
- and
- a control circuit configured to control the delivery of the neurostimulation using a plurality of stimulation parameters including one or more primary parameters each having a value selected for efficacy of the neurostimulation and one or more secondary parameters each having a value adjustable for preventing neural accommodation while maintaining the efficacy of the neurostimulation, the one or more primary parameters including a duty cycle being a ratio of an on-period to a sum of the on-period and an off-period, the on-period being a time period during which the neurostimulation is delivered, the off-period being a time period during which the neurostimulation is not delivered, the control circuit including a parameter adjuster configured to adjust the one or more secondary parameters without varying the one or more primary parameters including the duty cycle.
A method for delivering neurostimulation, comprising:
- delivering the neurostimulation;
- controlling the delivery of the neurostimulation using a plurality of stimulation parameters including one or more primary parameters each having a value selected for efficacy of the neurostimulation and one or more secondary parameters each having a value adjustable for preventing neural accommodation while maintaining the efficacy of the neurostimulation, the one or more primary parameters including a duty cycle being a ratio of an on-period to a sum of the on-period and an off-period, the on-period being a time period during which the neurostimulation is delivered, the off-period being a time period during which the neurostimulation is not delivered;
- and
- adjusting the one or more secondary parameters without varying the one or more primary parameters including the duty cycle.
A non-transitory computer-readable storage medium including instructions, which when executed by a system, cause the system to:
- delivering the neurostimulation;
- controlling the delivery of the neurostimulation using a plurality of stimulation parameters including one or more primary parameters each having a value selected for efficacy of the neurostimulation and one or more secondary parameters each having a value adjustable for preventing neural accommodation while maintaining the efficacy of the neurostimulation, the one or more primary parameters including a duty cycle being a ratio of an on-period to a sum of the on-period and an off-period, the on-period being a time period during which the neurostimulation is delivered, the off-period being a time period during which the neurostimulation is not delivered;
- and
- adjusting the one or more secondary parameters without varying the one or more primary, parameters including the duty cycle.
